A mixture of helium, argon, and xenon gases are present in a container. What is the partial pressure of helium if the total pressure is 49.2 kPa and the partial pressure of Ar is 15.6 kPa and 21,4 kPa for Xe?

Explanation:

Let assume that each gas behaves ideally, the total pressure is the sum of the pressures of each gas. Therefore:

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
